Doctor's answer:
At 4 weeks, the baby can see 25-30 centimeters wide at a 90-degree angle. By 3 months, they should be able to see 180 degrees and focus on the bottle. Hand-eye coordination develops by 4 months. Newborns can only briefly focus on one object, but by 1-2 months, they can better concentrate their gaze. At this time, colorful toys like balloons or plastic animals can be hung on the crib.
